Fix this by letting SUNW,fdtwo and sysbus-fdc both inherit from an
abstract type base-sysbus-fdc.
This allows to consolidate realizefns by using instance_init functions.
Clean up variable names and variable order while at it.

qemu-char: Register ring buffer driver with correct name "ringbuf"
The driver is new in 1.4, with the documented name "ringbuf".
However, it's actual name is the completely undocumented "memory".
Screwed up in commit 3949e59. Fix code to match documentation.
Keep the undocumented name working as an alias for compatibility.

Commit 51767e7 "qemu-char: Add new char backend CirMemCharDriver"
introduced a memory ring buffer character device driver named
"memory". Commit 3949e59 "qemu-char: Saner naming of memchar stuff &
doc fixes" changed the driver name to "ringbuf", along with a whole
bunch of other names, with the following rationale:
Naming is a mess. The code calls the device driver
CirMemCharDriver, the public API calls it "memory", "memchardev",
or "memchar", and the special commands are named like
"memchar-FOO". "memory" is a particularly unfortunate choice,
because there's another character device driver called
MemoryDriver. Moreover, the device's distinctive property is that
it's a ring buffer, not that's in memory.
This is what we released in 1.4.0.
Unfortunately, the rename missed a critical instance of "memory": the
actual driver name. Thus, the new device could be used only by an
entirely undocumented name. The documented name did not work.
Bummer.
Commit 6a85e60 fixes this by changing the documentation to match the
code. It also changes some, but not all related occurences of
"ringbuf" to "memory". Left alone are identifiers in C code, HMP and
QMP commands. The latter are external interface, so they can't be
changed.
The result is an inconsistent mess. Moreover, "memory" is a rotten
name. The device's distinctive property is that it's a ring buffer,
not that's in memory. User's don't care whether it's in RAM, flash,
or carved into chocolate tablets by Oompa Loompas.
Revert the commit. Next commit will fix just the bug.

Generator function get_expr() yields one section after the
other, as a string. An unindented, non-empty line that
isn't a comment starts a new section.
Lexing:
Split section into a list of tokens (strings), with help
of generator function tokenize().
Parsing:
Parse the first expression from the list of tokens, with
parse(), throw away any remaining tokens.
In parse_schema(): record value of an enum, union or
struct key (if any) in the appropriate global table,
append expression to the list of expressions.
Return list of expressions.
Known issues:
(1) Indentation is significant, unlike in real JSON.
(2) Neither lexer nor parser have any idea of source positions. Error
reporting is hard, let's go shopping.
(3) The one error we bother to detect, we "report" via raise.
(4) The lexer silently ignores invalid characters.
(5) If everything in a section gets ignored, the parser crashes.
(6) The lexer treats a string containing a structural character exactly
like the structural character.
(7) Tokens trailing the first expression in a section are silently
ignored.
(8) The parser accepts any token in place of a colon.
(9) The parser treats comma as optional.
(10) parse() crashes on unexpected EOF.
(11) parse_schema() crashes when a section's expression isn't a JSON
object.
Replace this piece of original art by a thoroughly unoriginal design.
Takes care of (1), (2), (5), (6) and (7), and lays the groundwork for
addressing the others. Generated source files remain unchanged.
